'lhie invention reletee to iinjoroifeiiiente in cider presses.

the priiiiary object ot the invention to provide eiinple and coiiipai'atively inert i ifieiieiye prese Weich will be practical flor do- :ind @ein the ii'iiicliineiy.

This arrangement ol the traine com tutee there'lfor a housing having an onen eide El. :troni which all 'the workingI parte ere :fic A' .le and the pressing' procese iouy be obeeii'cd. ljiacticully a ol the wut'liii le are uiipgioited by the eide 'well Suitable receptacle Such as il., Figi'. o.

an obvioue manner.

ing; Wheel il oit anyT suitable construction is placed. Fruit or other articles to be ground ere inserted in the open top ot the grinder and are ground between the grinding; Wheel El and one Wall ol the housing` and tall through 'the open bottoni 9 ol the housing' upon a coni/*eyeior belt 10. This belt may be of any suitable permeable itiibric. Iii the in'c'lerred coiietruction it may be of Wire ineeli. The conveyer belt ie carried by two main rollers il, 12, located near the end Walle ol the casing, and these rolle are car A l respectively on sbatte Illy l/t. The ten Sion i the belt is; -iuaiutaiued by roll 'l5 carried by a .elial't 1G and located near the bottoni ot the housing'. il lower pi'eseing roll 17 ie located near belt roll l2 below the belt and carried by a Shaft i8, and an upper preesiiigi' roll lll :is loco'tcd nearly directly above roll l? and is lined to a eheit 20. The couifcyci belt plissee between rolle l? and 19 and theee rolle are urged together by Suitable dm'iceeI leiter deecrilied eo that itruit pulp passing troni the griilder toward the rolle ie squeezed between thorn en d the uice extracted. lliie juice rune down and is caught by a trough 2l Secured at its bach to Wall l ot the czieingl conveniently by a thumb nut Q2. The trough has u spout 23 extendingl outward from the open .eide El o'l' the caeing to ii cori- Veiiieiit position tor discharging; juice into a guard ie placed above roll ll in a poeition to deflect juice dropping directly troni the `grinder* through the belt into trough This guard ie secured to Wall l olf the caeingl at and the securing device may he fi thuinh nut in ceses Where it is de eirable `to iiial-,zc the guard readily detachable.

il.. rotary brush il? ie preferably provided, located betweeii rolls l? and l2 and arranged to engage the under ei'irlace oit the conveyor belt. This; brush ie carried by a eliatt 28 ec'- ciired to wall 'l it 2).

It is desirable to ineke ull ot the rolle easily detachable troni their shafts. This detachable connection, as iii the cese of rolls il and l5, muy consiet in fi spring clip 30 connected to the roll und engaging e groove near the outer end ot the eheift. Then it is desired to remove the roll the Spring clip iii-ay be :moved up out olf the tfgioove and the roll pulled oil ol' the shalt, and replaced in lolle i2 and ld are cured to a, Het liiifli lll., which link; ie epee l l t) tured to receive the ends of the respective shafts 14 and 18. The numeral 32 designates a spring clip, the ends of which tit in grooves 32 near the ends of the shafts 14 and 18, the clip being prevented from moving upwardly by short pins 32 supported in the link.` XVith this construction when it is desired to remove the rolls.v it is only necessary to lift the ends' of the clip out of the grooves near the ends of the shafts when the clip may be removed laterally which will permit the removal of the link and free the ends of the shafts. The brush 28 and roll 19 may be secured by devices similar to those shown in connection with rolls 11 and 15. y

It is necessary to provide for movement of one of the rolls 17, 19, toward the other to provide yielding pressure for extracting the juice from the fruit pulp. Preferably, for this purpose, shaft 18 of roll 17 is mounted in a sleeve bearing 35 and the end of this is located in a vertically elongated slot 36 in side plate 1,. A spring 37, which spring 40.

may be a flat spring, bears against the lower side of the sleeve bearing. The spring is connected to the side plate at 38 and is tensioned by a pin 39. The outer or free end of shaft 18 may be connected to the outward end of shaft 20 by a helical contractile The two springs therefore urge both ends of shaft 18 upward and provide the Vnecessary yielding pressure between rolls 17 and 19.

Shaft 20 is provided with a sleeve bearing 41 fixed upon side plate 1. Beyond the bearing the shaft is provided with a sprocket wheel 42 and this is connected by belt or chain 43 with a sprocket wheel 44 on shaft 7. Shaft 7 is carried by a sleeve bearing 45 also fixed on side plate 1. A driving crank 46 may be connected to either shaft 7 or shaft 20. In this case it is shown connected to shaft 20 for driving the entire mechanism. The crank has a handle 47.

In some cases I provide the side wheel il with a scraper 51 which is arranged to bear against the conveyor belt to scrape from the belt, pulp from which the liuice hasl been extracted.

The general` operation is obvious from the previous description. 'lhe extraction ot juice is very effective and rapid, and in addition the entire machine and its 'parts may be quickly and easily clraned by 1nauipulatiing the quickly detachable fastenings of the different rolls and removingl the rolls with the conveyer belt, and when desired, also removing the trough 21 by loosening its thumb screw 22, and when cleaned theparts may be as readily replaced.

IVhat I claim is:

ln a fruit press or the like, the combination of a housing having an open side and a side wall, two conveyor belt rolls, a pcrlorate convcycr belt passing over the rolls, a tension roller engaging the lower stretch of the belt and located considerably below tlu` level of the other rolls, a lower pressure roll arranged between the two rolls tirst men` tioned and beneath the upper stretch of the belt, an upper pressure roll located above the upper stretch of the belt, n'ieans `l'or urging the pressure rolls together, a n'iovablc bearing for one of the pressure rolls located in the side wall of the housing, shafts for the other rolls, each shaft heilig connected at one end to said side wall, and means at the outer 'tree ends of such shafts tor .se curing their respective rolls detachably upon the shafts whereby the rolls and the con vcyer belt may be quickly removed for cleaning.

In testimony whereof I atlix my signature.

FREDERICK B. DAVIS.
